Description

Technical Field

[0001] This invention relates to the field of compression equipment technology, and in particular to a compressor and air conditioning unit. Background Technology

[0002] The basic structure of an existing rotary compressor is as follows: a drive motor consisting of a rotor and a stator is installed inside a sealed housing. The main shaft of the drive motor is connected to the rotor through a bushing perpendicular to the rotor. An eccentric shaft is connected to the lower end of the main shaft, and a rolling piston is fitted around the outer circumference of the eccentric shaft. The rolling piston is installed inside a cylinder, and the cylinder, together with the main bearing plate and the auxiliary bearing plate located at its upper and lower ends, forms a closed compression chamber. The air intake of the cylinder is connected to an external liquid storage tank, and the middle part of the liquid storage tank is integrated with the compressor housing through a central clamp and a bracket.

[0003] Because the receiver cannot be reliably fixed to the compressor housing, the rotating piston inside the cylinder causes the intake process to be periodic. The airflow in the intake pipe constantly switches between flowing and stationary states. Especially during compressor startup and shutdown, the airflow state switching impacts the inner wall of the receiver, causing relative vibration between the intake pipe and the receiver. Moreover, the compressor also vibrates during compression, causing the receiver to oscillate back and forth along the tangential range of the compressor cylinder, exacerbating the vibration of the intake pipe. This vibration of the intake pipe relative to the receiver can lead to leakage at the connection between the intake pipe and the receiver, resulting in reduced compressor reliability. Summary of the Invention

[0049] The basic structure of an existing rotary compressor is as follows: a drive motor consisting of a rotor and a stator is installed inside a sealed housing. The main shaft of the drive motor is connected to the rotor through a bushing perpendicular to the rotor. An eccentric shaft is connected to the lower end of the main shaft, and a rolling piston is fitted around the outer circumference of the eccentric shaft. The rolling piston is installed inside a cylinder, and the cylinder, together with the main bearing plate and the auxiliary bearing plate located at its upper and lower ends, forms a closed compression chamber. The air intake of the cylinder is connected to an external liquid storage tank, and the middle part of the liquid storage tank is integrated with the compressor housing through a central clamp and a bracket. In existing technologies, to address the vibration of the suction pipe, the fixation between the liquid storage tank and the shell is typically increased. This can be achieved by increasing the number of fixing structures between the liquid storage tank and the shell, thereby increasing the fixation effect and reducing the vibration transmitted from the shell to the liquid storage tank. This, in turn, reduces the relative vibration between the suction pipe and the liquid storage tank. However, even with some degree of fixation, it is impossible to completely eliminate the problem of unequal vibration frequencies and amplitudes of the liquid storage tank due to the separate structure of the suction pipe and the liquid storage tank. Therefore, this application provides... Figures 1 to 9 The compressor shown includes: a liquid storage tank 1; a suction pipe 2 connected to the liquid storage tank 1; a vertical vibration absorption structure 3, the lower end of which is disposed on the liquid storage tank 1 and the upper end of which is connected to the suction pipe 2; and a circumferential vibration absorption structure 4, the first end of which is connected to the vertical vibration absorption structure 3 and the second end of which is connected to the suction pipe 2. The suction pipe 2 and the liquid storage tank 1 are connected by a vertical vibration-absorbing structure 3 and a circumferential vibration-absorbing structure 4. The vertical vibration-absorbing structure 3 can suppress the vertical vibration of the suction pipe 2 and increase the vertical stiffness of the suction pipe 2. The circumferential vibration-absorbing structure 4 can suppress the horizontal vibration of the suction pipe 2 and increase the circumferential stiffness of the suction pipe 2. In particular, it can suppress the phenomenon of damage and breakage at the connection between the suction pipe 2 and the liquid storage tank 1 when the liquid storage tank 1 is oscillating back and forth, which is caused by the different oscillation frequencies and amplitudes of the suction pipe 2 and the liquid storage tank 1. This improves the integrity of the suction pipe 2 and the liquid storage tank 1, and can suppress the vibration of the suction pipe 2 in multiple directions. It avoids the problem of damage and breakage of the suction pipe 2 in the prior art and improves the reliability of the compressor.

[0050] Specifically, the vertical vibration-absorbing structure 3 includes a first elastic element 31. The lower end of the first elastic element 31 is disposed on the liquid storage tank 1, and the upper end of the first elastic element 31 is connected to the suction pipe 2. The first elastic element 31 can undergo elastic deformation. Since the lower end of the first elastic element 31 is disposed on the liquid storage tank 1, and the upper end is disposed on the suction pipe 2, when the suction pipe 2 vibrates vertically or when there is a vertical component in the vibration of the suction pipe 2, the first elastic element 31 will deform with the vibration of the suction pipe 2, thereby reducing the vibration frequency and vibration amplitude of the suction pipe 2, increasing the connection strength between the suction pipe 2 and the liquid storage tank 1, and improving the integrity between the suction pipe 2 and the liquid storage tank 1. This reduces the problem of unreliable connection between the suction pipe 2 and the liquid storage tank 1 caused by vertical vibration, avoids the problem of damage and breakage of the suction pipe 2 in the prior art, and improves the reliability of the compressor. Meanwhile, since the suction pipe 2 vibrates and swings, and the swing of the suction pipe 2 is centered on the connection position between the suction pipe 2 and the liquid storage tank 1, the swing amplitude of the position of the suction pipe 2 corresponding to the upper end of the first elastic element 31 is much greater than the swing amplitude of the connection position between the suction pipe 2 and the liquid storage tank 1. At this time, the suction pipe 2 will also swing along with the first elastic element 31, which will also cause the first elastic element 31 to undergo elastic deformation to suppress the swing of the suction pipe 2, thereby achieving the purpose of suppressing the circumferential vibration of the suction pipe 2. This achieves the suppression of multi-directional vibration of the suction pipe 2, avoids the problem of the suction pipe 2 breaking and leaking due to vibration, and effectively improves the reliability of the compressor.

[0051] Due to the varying operating environments of the compressor, the direction in which the liquid storage tank 1 drives the suction pipe 2 to swing is uncertain. Therefore, the suction pipe 2 has multiple first elastic elements 31, all of which are arranged in a ring around the suction pipe 2. By utilizing multiple first elastic elements 31 simultaneously to suppress the swinging and vertical vibration of the suction pipe 2, the vibration damping effect of the vertical vibration absorption structure 3 on the suction pipe 2 is improved. Furthermore, when the suction pipe 2 swings in one direction, the first elastic element 31 in that direction is compressed and undergoes elastic deformation, while the first elastic element 31 in the opposite direction is stretched and undergoes elastic deformation, further increasing the suppression of the swinging of the suction pipe 2 and enhancing its vibration damping effect.

[0052] like Figure 2 and Figure 3As shown, the first elastic element 31 includes a first straight plate structure 311 and a second straight plate structure 312 connected to each other, and there is an included angle between the first straight plate structure 311 and the second straight plate structure 312. The first straight plate structure 311 is arranged along a vertical plane, and the lower end of the first straight plate structure 311 is connected to the liquid storage tank 1. The second straight plate structure 312 is inclined relative to the vertical plane toward the suction pipe 2. When the suction pipe 2 vibrates, the end of the second straight plate structure 312 connected to the suction pipe 2 can move with the vibration of the suction pipe 2, so that the included angle between the first straight plate structure 311 and the second straight plate structure 312 changes and forms elastic deformation. At this time, the first straight plate structure 311 and the second straight plate structure 312 have the ability to restore the initial included angle, thereby suppressing the vibration of the suction pipe 2 and effectively reducing the vibration of the suction pipe 2.

[0053] Taking the vertical vibration component in the vibration of the suction pipe 2 as an example, when the suction pipe 2 vibrates in the vertical direction, it will also drive the end of the second straight plate structure 312 to move in the vertical direction. However, the end of the second straight plate structure 312 connected to the first straight plate structure 311 cannot move. The movement of the suction pipe 2 can be transmitted to the second straight plate structure 312 and the first straight plate structure 311. When the suction pipe 2 moves downward, the second straight plate structure 312 tilts downward, and the first straight plate structure 311 is squeezed and flipped outward. At this time, the second straight plate structure 312 has the ability to move upward, and the first straight plate structure... 311 has the ability to restore the shape of the flat plate. Both of these abilities can drive the suction pipe 2 to move upward, thereby counteracting the vibration of the suction pipe 2 moving downward. Conversely, when the suction pipe 2 moves upward, the second straight plate structure 312 tilts upward, and the first straight plate structure 311 is stretched and flipped inward. At this time, the second straight plate structure 312 has the ability to move downward, and the first straight plate structure 311 has the ability to restore the shape of the flat plate. Both of these abilities can drive the suction pipe 2 to move downward, thereby counteracting the vibration of the suction pipe 2 moving upward. Both can achieve the effect of suppressing the vibration of the suction pipe 2.

[0054] Similarly, when the suction pipe 2 swings, the first straight plate structure 311 and the second straight plate structure 312 will also deform. When the suction pipe 2 tilts in a certain direction, the first elastic element 31 in this direction and nearby is compressed, the second straight plate structure 312 tilts downward, and the first straight plate structure 311 is squeezed and flipped outward. Meanwhile, the second straight plate structure 312 in the opposite direction tilts downward, and the first straight plate structure 311 is stretched and flipped inward. At this time, all the first elastic elements 31 will give the suction pipe 2 a force to tilt in the opposite direction, thereby suppressing the movement direction of the suction pipe 2 and also suppressing the vibration of the suction pipe 2.

[0055] like Figure 3As shown in the figure, there are four first elastic elements 31. The two adjacent first elastic elements 31 form a 90° angle, so that when the air pipe 2 swings in any direction, at least one first elastic element 31 is squeezed and produces elastic deformation, and at least one first elastic element 31 is stretched and produces elastic deformation, thus ensuring the vibration reduction effect on the air pipe 2.

[0056] To facilitate the connection between the first elastic element 31 and the liquid storage tank 1, the vertical vibration-absorbing structure 3 further includes a first annular element 32. The first annular element 32 is disposed on the liquid storage tank 1, and the lower ends of all the first elastic elements 31 are disposed on the first annular element 32. The first annular element 32 is sleeved on the liquid storage tank 1, and reliable fixation with the liquid storage tank 1 is achieved by friction. The first annular element 32 includes two interlocking semicircular parts. When installing the first annular element 32, the two semicircular parts are disassembled and then installed on the liquid storage tank 1 from both sides. Then, the two semicircular parts are connected to each other, thereby realizing the installation of the first annular element 32 and the liquid storage tank 1. The first annular member 32 forms an annular mounting platform. The lower end of the first elastic member 31 is disposed on the mounting platform. In particular, the lower end of the first elastic member 31 is provided with a bent portion, and the bent portion is located on the side of the first elastic member 31 facing the suction pipe 2. This allows the bent portion to provide some support for the elastic deformation of the first elastic member 31 when the first elastic member 31 undergoes elastic deformation, and also to undergo a certain elastic deformation together with the first elastic member 31, thereby improving the elastic deformation capability of the first elastic member 31. Figure 2 and Figure 3 As shown, the lower end of the first straight plate structure 311 is bent. When the first straight plate structure 311 is squeezed and flipped outward or stretched and flipped inward, the first straight plate structure 311 flips at the connection position between the first straight plate structure 311 and the bent part. As the first straight plate structure 311 flips, the included angle between the first straight plate structure 311 and the bent part also changes. The first straight plate structure 311 and the bent part also have the ability to restore the included angle to a preset angle. This ability will force the first straight plate structure 311 to return to a vertical state, thereby improving the vibration suppression effect of the first elastic member 31 on the air intake pipe 2.

[0057] To facilitate the connection of the first elastic element 31 to the suction pipe 2, the vertical vibration-absorbing structure 3 further includes a second annular element 33. The second annular element 33 is located above the first annular element 32 and is disposed on the suction pipe 2. The upper ends of all the first elastic elements 31 are disposed on the second annular element 33. The second annular element 33 is used to encircle the suction pipe 2, and then the upper ends of the first elastic elements 31 are connected to the second annular element 33, thereby fixing the first elastic element 31. The second annular element 33 includes two semi-circular components. The two semi-circular components are brought close to the suction pipe 2 from both sides, and then locked together, thereby ensuring reliable fixation of the upper ends of the first elastic elements 31 to the suction pipe 2, and ensuring that the vibration of the suction pipe 2 can drive the upper ends of the first elastic elements 31 to move. The second annular component 33 is provided with an annular mounting platform. The upper end of the first elastic component 31 is mounted on the mounting platform, and the upper end of the first elastic component 31 is also provided with a bent portion. The bent portion is located on the side of the first elastic component 31 facing the suction pipe 2, so that when the first elastic component 31 undergoes elastic deformation, the bent portion can provide certain support for the elastic deformation of the first elastic component 31, and can also undergo a certain elastic deformation together with the first elastic component 31, thereby improving the elastic deformation capability of the first elastic component 31. Figure 2 and Figure 3 As shown, the upper end of the second straight plate structure 312 has a bent portion. When the second straight plate structure 312 is squeezed and tilted upward or downward, the second straight plate structure 312 flips at the connection position between the second straight plate structure 312 and the bent portion. As the second straight plate structure 312 flips, the included angle between the second straight plate structure 312 and the bent portion also changes. Furthermore, the second straight plate structure 312 and the bent portion also have the ability to restore the included angle to a preset angle. This ability forces the second straight plate structure 312 to return to a vertical state, thereby improving the vibration suppression effect of the first elastic member 31 on the suction pipe 2.

[0058] Furthermore, a vibration damping pad is provided between the second annular component 33 and the air intake pipe 2. The vibration damping pad further absorbs the vibration of the air intake pipe 2, thereby improving the vibration damping effect of the vertical vibration absorption structure 3.

[0059] The vibration damping pads include a metal vibration damping pad 34 and a deformation vibration damping pad 35. The metal vibration damping pad 34 is disposed on the suction pipe 2, and the deformation vibration damping pad 35 is disposed between the metal vibration damping pad 34 and the second annular member 33. The reason for using the metal vibration damping pad 34 to directly contact the suction pipe 2, instead of using the deformation vibration damping pad 35 to directly contact the suction pipe 2, is that without the metal vibration damping pad 34, the frequency of the vertical vibration absorption structure 3 would be very low, failing to reach the compressor's operating frequency of 50Hz. Therefore, the addition of the metal vibration damping pad 34 increases the vibration absorption frequency of the vertical vibration absorption structure 3, thereby increasing its vibration damping effect. Preferably, the deformation vibration damping pad 35 is a rubber pad, forming a metal-rubber-metal vibration damping system. The deformation of the rubber further absorbs vibrations, thereby increasing the vibration damping effect of the vertical vibration absorption structure 3.

[0060] Furthermore, the formula for the vibration absorption frequency is:

[0061]

[0062] Therefore, the vibration absorption frequency of the vertical vibration-absorbing structure 3 can be adjusted by changing its mass. The vertical vibration-absorbing structure 3 also includes a vertical counterweight 36, which is disposed on the second annular member 33, and the number of vertical counterweights 36 is adjustable. By changing the mass of the vertical vibration-absorbing structure 3 using the vertical counterweights 36, the vertical frequency of the vertical vibration-absorbing structure 3 can be changed. When the vertical counterweights 36 are increased, the vertical frequency of the vertical vibration-absorbing structure 3 decreases; when the vertical counterweights 36 are decreased, the vertical frequency of the vertical vibration-absorbing structure 3 increases. Preferably, the adjustment range of the vertical frequency of the vertical vibration-absorbing structure 3 is 30Hz to 50Hz, thereby increasing the vibration reduction effect of the vertical vibration-absorbing structure on the intake pipe 2.

[0063] The circumferential vibration-absorbing structure 4 includes a third annular member 41 and a second elastic member 42. The third annular member 41 is disposed on the vertical vibration-absorbing structure 3. One end of the second elastic member 42 is disposed on the third annular member 41, and the other end is connected to the air intake pipe 2. The second elastic member 42 can generate elastic deformation in the horizontal direction. The elastic deformation generated by the second elastic member 42 suppresses the swaying of the air intake pipe 2, thereby reducing the swaying of the air intake pipe 2. Moreover, since the end of the second elastic member 42 away from the air intake pipe 2 is disposed on the vertical vibration-absorbing structure 3 through the third annular member 41, the second elastic member 42 can reliably generate deformation to suppress the air intake pipe 2, achieving the effect of vibration reduction of the air intake pipe 2. The third annular component 41 is positioned between the first annular component 32 and the second annular component 33, thereby limiting the suction pipe 2 at different heights and effectively improving the limiting effect on the suction pipe 2. Furthermore, since the first annular component 32 is positioned on the liquid storage tank 1, the structural strength of the connection between the suction pipe 2 and the liquid storage tank 1 is improved, avoiding the problem of unreliable vibration between the suction pipe 2 and the liquid storage tank 1 in the prior art, which could cause the suction pipe 2 to break or be damaged, thus ensuring the reliability of the compressor.

[0064] To facilitate the connection of the second elastic element 42 to the suction pipe 2, the circumferential vibration-absorbing structure 4 further includes a fourth annular element 43. The fourth annular element 43 is disposed on the suction pipe 2. One end of the second elastic element 42 abuts against the third annular element 41, and the other end abuts against the fourth annular element 43. By reliably fixing the fourth annular element 43 to the suction pipe 2, and then connecting the end of the second elastic element 42 to the fourth annular element 43, a reliable connection between the second elastic element 42 and the suction pipe 2 can be achieved. Optionally, the second elastic element 42 can be a spring.

[0065] The circumferential vibration-absorbing structure 4 also includes a connecting rod 44. A first through hole is provided on the third annular member 41. One end of the connecting rod 44 is disposed on the fourth annular member 43, and the other end protrudes from the third annular member 41 through the first through hole. The second elastic member 42 is sleeved on the connecting rod 44. The connecting rod 44 and the third annular member 41 are not connected; the first through hole only restricts the movement of the connecting rod 44 in a non-axial direction, allowing it to move only along its axis. Similarly, this also limits the deformation of the second elastic member 42 to the axial direction of the connecting rod 44, ensuring reliable deformation of the second elastic member 42. Especially when the second elastic member 42 is a spring, it avoids the influence of gravity on the spring, preventing the middle of the spring from deforming downwards, thus ensuring reliable spring deformation.

[0066] The circumferential vibration-absorbing structure 4 also includes a limiting member 45, which is disposed on the connecting rod 44 and located on the side of the third annular member 41 away from the fourth annular member 43. The position of the limiting member 45 on the connecting rod 44 is adjustable. The limiting member 45 restricts the movement distance of the connecting rod 44 in the axial direction, preventing the connecting rod 44 from disengaging from the third annular member 41. At the same time, the position of the limiting member 45 can be adjusted to adjust the deformation capacity of the second elastic member 42, thereby adjusting the circumferential stiffness of the circumferential vibration-absorbing structure 4.

[0067] like Figure 7 As shown, the initial position of the limiting member 45 is L away from the third annular member 41. When the limiting member 45 moves to the position shown, the distance between the limiting member 45 and the third annular member 41 is L. Figure 8 When the position shown changes, the positions of the two opposing limiting members 45 on the corresponding connecting rod 44 change. The distance between one limiting member 45 and the third annular member 41 becomes 2L, while the distance between the other limiting member 45 and the third annular member 41 becomes 0. At this time, one of the second elastic members 42 is compressed, and the shape of the other second elastic member 42 changes. The horizontal stiffness increases, which increases the horizontal vibration frequency of the circumferential vibration absorption structure 4, thus increasing the suppression of the circumferential vibration of the intake pipe 2. Conversely, adjusting the limiting member 45 away from the third annular member 41 decreases the horizontal stiffness, which decreases the horizontal vibration frequency of the circumferential vibration absorption structure 4.

[0068] When the second elastic element 42 is compressed or stretched to its limit size, the third annular element 41 also deforms, achieving a two-stage vibration reduction effect in the horizontal direction.

[0069] To ensure a reliable connection between the fourth annular component 43 and the suction pipe 2, a vibration damping pad is provided between the fourth annular component 43 and the suction pipe 2. The vibration damping pad increases the reliability of the connection between the fourth annular component 43 and the suction pipe 2.

[0070] like Figures 6 to 8 As shown, there are multiple second elastic elements 42, and all second elastic elements 42 are evenly distributed between the air intake pipe 2 and the third annular member 41, so that the vibration of the air intake pipe 2 in any direction can be suppressed, ensuring the vibration reduction effect of the air intake pipe 2.

[0071] Preferably, the third annular member 41 is an annular leaf spring, meaning that the third annular member 41 can undergo elastic deformation. Thus, when the first elastic member 31 deforms, the third annular member 41 can also deform accordingly, increasing the reset capability of the vertical shock-absorbing structure. Moreover, the deformation capability of the third annular member 41 can also increase the adjustable range of the limiting member 45 on the connecting rod 44, thereby increasing the adjustment range of the deformation capability of the second elastic member 42, and further increasing the range of the circumferential frequency of the circumferential vibration-absorbing structure 4.

[0072] To further improve the vibration reduction and absorption effect of the circumferential vibration-absorbing structure 4, the circumferential vibration-absorbing structure 4 also includes a circumferential counterweight 46, which is movably mounted on the third annular member 41. The circumferential counterweight 46 increases the circumferential frequency adjustment range of the circumferential vibration-absorbing structure 4. When the weight of the circumferential counterweight 46 increases, the mass of the circumferential vibration-absorbing structure 4 increases, and the absorption frequency decreases; conversely, when the weight of the circumferential counterweight 46 decreases, the mass of the circumferential vibration-absorbing structure 4 decreases, and the absorption frequency increases, thereby improving the vibration reduction effect of the circumferential vibration-absorbing structure 4. In particular, to ensure that the circumferential counterweight 46 can reliably move on the third annular member 41 and can be reset, the circumferential vibration-absorbing structure 4 also includes a third elastic member 47. The circumferential counterweight 46 is connected to the third annular member 41 through the third elastic member 47, and the third elastic member 47 can generate elastic deformation in the horizontal direction. When the circumferential counterweight 46 moves, the corresponding third elastic element 47 can generate elastic deformation, allowing the circumferential counterweight 46 to move. Moreover, the elasticity of the third elastic element 47 can drive the circumferential counterweight 46 to reset, ensuring that the circumferential counterweight 46 can move synchronously with the vibration of the air intake pipe 2, thereby improving the vibration reduction effect of the circumferential vibration absorption structure 4.

[0073] Since the circumferential counterweight 46 is affected by gravity, a strip-shaped hole 411 is provided on the third annular member 41. The circumferential counterweight 46 is movably disposed at the strip-shaped hole 411. One end of the third elastic member 47 abuts against the edge of the strip-shaped hole 411, and the other end abuts against the circumferential counterweight 46. The strip-shaped hole 411 restricts the movement of the circumferential counterweight 46, preventing it from moving downwards due to gravity, ensuring the reliable position of the circumferential counterweight 46, and thus improving the reliability of the circumferential vibration absorption structure 4. Preferably, a guide groove 461 is provided on the lower end surface of the circumferential counterweight 46, and the guide groove 461 guides and engages with the lower edge of the strip-shaped hole 411. The guide groove 461 and the lower edge of the strip hole 411 are used for guidance, restricting the circumferential counterweight 46 to move only along the strip hole 411, further ensuring the reliable movement of the circumferential counterweight 46. At the same time, under the action of gravity, the circumferential counterweight 46 will move downward, thereby ensuring the reliable fit between the guide groove 461 and the lower edge of the strip hole 411, and preventing the circumferential counterweight 46 from detaching from the third annular member 41.

[0074] Alternatively, a guide groove 461 may be provided on the upper end surface of the circumferential counterweight 46, and the guide groove 461 may engage with the upper edge of the strip hole 411. By using the guide groove 461 and the upper edge of the strip hole 411 for guidance, the movement of the circumferential counterweight 46 is restricted to along the strip hole 411, further ensuring the reliable movement of the circumferential counterweight 46. In this case, the edge of the guide groove 461 needs to be higher than the edge of the strip hole 411, thus preventing the circumferential counterweight 46 from moving downwards and detaching from the third annular component 41 under the influence of gravity.

[0075] Preferably, guide grooves 461 are provided on both the upper and lower end faces of the circumferential counterweight 46, and the guide grooves 461 are engaged with the corresponding edges of the strip hole 411, thereby restricting the circumferential counterweight 46 from both the upper and lower directions. The circumferential counterweight 46 can only move along the strip hole 411, ensuring reliable movement and position of the circumferential counterweight 46.

[0076] like Figure 9As shown, the circumferential counterweight 46 includes a locking member and at least two counterweight blocks. All the counterweight blocks are disposed on the locking member, and a guide groove 461 is formed between two adjacent counterweight blocks. The locking member secures the counterweight blocks, facilitating the adjustment of the number of counterweight blocks and thus the weight of the circumferential counterweight 46. Furthermore, the direct formation of the guide groove 461 by the counterweight blocks facilitates the installation of the circumferential counterweight 46. The two counterweight blocks used to form the guide groove 461 can be installed from both sides of the third annular member 41 towards the slotted hole 411, and then locked using the locking member. At this point, the two counterweight blocks are precisely positioned on both sides of the upper and lower edges of the slotted hole 411, ensuring a reliable fit between the guide groove 461 formed between the two counterweight blocks and the slotted hole 411.

[0077] The circumferential counterweights 46 are multiple in number and are evenly distributed on the third annular member 41. By using multiple circumferential counterweights 46 to adjust the weight at different positions of the third annular member 41, the vibration reduction effect of the circumferential vibration-absorbing structure 4 is further improved.

[0078] The circumferential vibration-absorbing structure 4 can move vertically on the vertical vibration-absorbing structure 3. By adjusting the position of the circumferential vibration-absorbing structure 4 in the vertical direction, the position in which the circumferential vibration-absorbing structure 4 supports the air intake pipe 2 can be adjusted, thereby improving the vibration reduction effect on the air intake pipe 2. Furthermore, the center of gravity of the vertical vibration-absorbing structure can be further adjusted, thereby improving the vibration reduction effect of the vertical vibration-absorbing structure 3.

[0079] like Figure 3 As shown in the figure, a vertical strip hole 313 is provided on the first elastic element 31, and the connecting rod 44 passes through the vertical strip hole 313. At this time, adjusting the position of the connecting rod 44 in the vertical strip hole 313 can realize the vertical position adjustment of the circumferential vibration absorption structure 4. Furthermore, since the limiting element 45 is provided on the connecting rod 44, the circumferential vibration absorption structure 4 can be locked onto the vertical vibration absorption structure 3 by the compression of the first elastic element 31 by the limiting element 45, thus completing the installation of the circumferential vibration absorption structure 4.

[0080] Alternatively, the number of circumferential vibration-absorbing structures 4 is at least two, and all the circumferential vibration-absorbing structures 4 are arranged side by side in the vertical direction on the vertical vibration-absorbing structure 3. That is, multiple circumferential vibration-absorbing structures 4 are provided to simultaneously restrict the suction pipe 2, which fully improves the circumferential stiffness of the suction pipe 2, so that the suction pipe 2 and the liquid storage tank 1 form an integral structure, avoiding the problem of the suction pipe 2 breaking at the connection position between the suction pipe 2 and the liquid storage tank 1, and improving the reliability of the compressor.

[0081] Of course, the compressor also includes a housing 5, and the liquid storage tank 1 is mounted on the housing 5 and fixed by a fixing strap or the like to achieve the connection between the liquid storage tank 1 and the housing 5.

[0082] An air conditioning unit includes the compressor described above.

[0083] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
